I Have some confusion which I want to share so anyone with deep knowledge can clear it.
Im working on a interior project, with all things setup!! My light map building time is around 4 hours. My PC is Core i3 3.3Ghz 2Core 4 Thread, with 8GB ram and ATI-7770 GPU.
I got a Macbook which is Core i7 2.0Ghz 4Core 8 Thread, 8GB ram but the GPU is Intel. I copied My project to Mac and Rebuild the lights! and I was hoping its i7 so the render time should be less, But interesting thing is Macbook also too the same 4 hours to build the same result.
I see somewhere on this forum someone was saying, For light Map calculation Unreal engine uses the CPU and for exporting light maps it uses GPU. (If this is right)
So my 1st Question is the Macbook CPU is more Power full then my desktop CPU but still the render time was the same! is it because of the intel GPU?
Second Question: If I install Windows on Macbook and use it via network to render the lightmap along with my desktop. Will it be faster? I didnt tried it yet!
